I have had this warning, too. The solution was to add the USER to the 
group netdev.

acertux:~# adduser USER netdev

Furthermore u have to restart the dbus-daemon.

acertux:~# /etc/init.d/dbus restart

I do not know, if this helps, because my problem was another one, but 
one warning less is better than nothing i thougt.
